Title: Electric discharge machine
Inventor: WATANABE HARUMI
IPC: B23H1/02
Filed: 1986-01-31
Abstract: PURPOSE:To prevent melted working chips produced by electric discharge machining from depositing to a workpiece and thus provide a high quality stable working surface by adding mechanical vibration such as super sonic vibration to the workpiece in the electric discharge machining. CONSTITUTION:A workpiece 1 fixed to a mounting body 8 is immersed in working liquid 5a and an electrode 9 is brought close to the workpiece 1 by a feed mechanism 11. Predetermined voltage is applied from a voltage applying section 4 to carry out electric discharging machining during which super-sonic wave vibration from a generator 13 is applied to the mounting body 8, i.e. workpiece 1 by a super sonic horn 12 in a vibration adding section 6. Thus, melted spatters produced by the electric discharge machining and working liquid 5a are vibrated so that an average passage of the melted spatters reaching the surface of the workpiece 1 is elongated, and since the workpiece 1 is vibrated, the melted spatters are hard to be attached. Even if they are attached, they can be easily removed since they are unstable. Thus, a high quality stable working surface is provided.

Title: Ink ribbon feeding mechanism
Inventor: SAMU ATSUSHI
IPC: B41J33/36
Filed: 1985-01-31
Abstract: PURPOSE:To contrive higher printing quality and higher printing speed through a reduction in the region in which the relative velocity of a carriage and an ink ribbon is raised, by setting the gear ratio in an ink ribbon feeding driving means so that the velocity of the ribbon being moved in a direction opposite to the moving direction of the carriage is low. CONSTITUTION:The ink ribbon feeding driving means comprises a gear 9, a planetary gear 11 rotatably supported on a gear shaft 11a fixed to a planetary gear support plate 10, the first driven gear 12, an ink ribbon driving gear 13, and the second and third driven gears 15, 14, and is fitted to a substrate 16. When a timing belt 5 is driven to move the carriage 1 in a direction A and a direction B, the ink ribbon driving gear 13 is rotated CCW in both cases, so that the ribbon 19 is fed in a constantly fixed direction. Where the ribbon velocity is UR (characters/sec) and the carriage velocity is UC (characters/sec), the relative velocity of the carriage and the ribbon is UC-UR when the carriage is moved in the direction A, and is UC+UR when the carriage 1 is moved in the direction B. Thus, the relative velocity is varied depending on the driving direction of the carriage. Therefore, in order to efficiently use the ribbon 19, it is necessary to set UR to be low.

Title: Comb-line type elastic surface wave device
Inventor: YAMADA JIYUN
IPC: H03H9/64
Filed: 1979-02-21
Abstract: PURPOSE:To secure the constant frequency interval of the mount or the bottom within the desired band by securing the electrode pitch reduced more and more at the closer side toward the partner electrode for at least one of the roller screen type electrodes of the output side which are connected in parallel. CONSTITUTION:Input-side electrode 2 plus output-side electrodes 3' and 4' connected in parallel are distributed on piezoelectric substrate 1. Electrode pitch L of electrode 3' is reduced more and more at the side closer to electrode 4'. Thus the elastic surface wave excited by electrode 2 propagates the longer route the higher the frequency, and accordingly the delay time is increased. On the contrary, the higher the frequency the smaller the delay time with electrode 4'. If the delay time between electrodes 3' and 4' is set constant within the desired frequency band, the constant frequency interval can be secured for the mount or the bottom of the comb-line characteristics.

Abstract: PURPOSE:To make a paper refeed cassette utilizable as a copying paper receiving device as well, by installing a selector device which selects a passage for the copying paper discharged out of a copying machine body into two parts, or the paper discharge tray side and the paper refeed cassette side. CONSTITUTION:In case of a paper discharge tray mode, a first selector claw 60 is situated at the lower step, and the copying paper discharged out of a pair of paper discharge rollers 21 of a copying machine body 1 is fed onto a paper discharge tray 45. On the other hand, when a paper refeed cassette 50 is utilized as a copying paper receiving device, both first and second selector claws 60 and 65 are selected to the upper step, the copying paper to be discharged out of the paired paper discharge rollers 21 is guided by a guide plate 70, conveying it with rollers 71 and 72, and further it is guided to a lower surface of the selector claw 65, having it fed to the inside of the paper refeed cassette 50. Thus, since the paper refeed cassette is utilizable as a copying paper receiving device as well as a paper feeding device, installation of any other separate paper discharge tray is no longer required.

Filed: 1995-01-12
Abstract: PURPOSE: To set a test piece at a predetermined position on a stage by delivering a monitor signal, related to the position of the test piece mounted on the stage, to a control section thereby correcting the position of the test piece. CONSTITUTION: The lift 4 for a cassette 1 is elevated and a transfer arm 7 sucks 12 a test piece 2 from a test piece case 3. A transfer unit 6 moves along with the base end part 10 above a test piece stage 14 and the arm 7 transfers the test piece 2 onto the stage 14. A monitoring mechanism 19 disposed directly above the stage 14 monitors the position of the test piece 2 on the stage 14 using a monitor camera 19A having a square effective visual field defined within a circular visual field. Each critical position of the test piece 2 within the effective visual field is represented in the form of the difference from a reference point using a pixel signal which is then processed through a processing mechanism 19B to produce a numeric positional signal.  The signal is delivered to the horizontal rotary mechanism and the horizontal moving mechanism supporting the stage 14 which is thereby moved to correct the difference thus setting the test piece 2 at a predetermined position.

Title: Interrupting method for transmission procedure of facsimile
Inventor: OGASAWARA FUMIHIRO
IPC: H04M11/00
Filed: 1981-02-13
Abstract: PURPOSE:To achieve immediate line cut on the opposing set even before the establishment of hand-shake, by transmitting a procedure intermitting signal and a line cut-off signal, when the procedure of transmissioin is interrupted. CONSTITUTION:In interrupting the means of transmission for a facsimile device (G3+G2 machine) provided with G3 and G2 functions, after a line cut-off instruction DCN signal used with the G3 function mode and a step iterruption signal PIS used in the G2 function mode are both transmitted, the lines are disconnected. As a result, even if the G3+G2 machine makes a trouble and the procedure is interrupted before the establishment of hand-shake at a called station  side, since signals PIS and DCN are returned to a calling station side, the lines  can be cut off immediately. Thus, useless employment of lines is elminated.
